Hi, I just reached level 110 with my dark night. I was doing the Apocalypse mission but mistakenly abandoned it. How can i get it back? duke lankral will no longer appear to me.
Your best bet is going to be to trace a path through the questline to see where you can pick it up again. The quest itself looks like it should pop up automatically when your character goes to Dalaran. So, that would be the first thing to try to pick it up again. (If you’re already in Dalaran, try logging in an out or leaving Dalaran and coming back.)
If that doesn’t work, I’d go to the quest turn in location and see if you can proceed from there.
The wowhead page for the quest has the whole series listed, so you can try to find your place using that.
